Aims Asthma, hay fever and eczema are three common chronic conditions. There have been no recent multi-country data on the burden of these conditions in adults; aims this study to fill evidence gap. Methods The Global Asthma Network Phase I is a cross-sectional population-based using same core methodology as International Study Allergies Childhood III. It provides asthma, children adolescents, and, for first time, their parents/guardians. Results Data were available from 193 912 adults (104...

A validated, written questionnaire was distributed via schools three age groups (children, 6–7 years; adolescents, 13–14 adults, ≥19 years). Eligible...
Abstract Background Eczema (atopic dermatitis) is a major global public health issue with high prevalence and morbidity. Our goal was to evaluate eczema over time, using standardized methodology. Methods The Global Asthma Network (GAN) Phase I study an international collaborative arising from the International Study of Allergies in Children (ISAAC). Using surveys, we assessed prevalence, severity, lifetime centres participating GAN (2015–2020) one/ both ISAAC (1993–1995) III (2001–2003). We...

Patients with asthma need uninterrupted supplies of affordable, quality-assured essential medicines. However, access in many low- and middle-income countries (LMICs) is limited. The World Health Organization (WHO) Non-Communicable Disease (NCD) Global Action Plan 2013⁻2020 sets an 80% target for NCD medicines' availability. Poor partly due to medicines not being included on the national Essential Medicines Lists (EML) and/or National Reimbursement (NRL) which guide provision free/subsidised...

<b>Background:</b> Asthma patients in high-income countries (HIC) and low- middle-income (LMIC) need uninterrupted supplies of affordable, quality-assured essential medicines. The World Health Organization (WHO) NonCommunicable Disease (NCD) Global Action Plan sets an 80% target for availability NCD Access is likely to improve if medicines are on national Essential Medicines Lists (EML) provided free/subsidised. <b>Methods:</b> Principal investigators the Network were sent a questionnaire...
<b>Background:</b> Asthma affects more than 300 million people globally, many of whom are undertreated, and thus unnecessarily disabled. Some countries have developed effective asthma strategies, which, when consistently implemented, result in reduction the burden to individuals society (Haahtela T et al. National Strategies.
